Higher still, the tower shows you a scene from the past — a traveller meddling with fate, yet somehow you are still here. Multiple timelines weave before your eyes, some allowing your birth, others denying it. The answer hides in the odds.
Question:
A time traveller goes back and prevents their grandfather from meeting their grandmother. But paradoxically, they still exist. The temporal mechanics explain: there are 5 parallel timelines. In 3 timelines, the grandfather meets the grandmother. In 2 timelines, he doesn’t. What is the probability (as a percentage) that a randomly selected timeline allows the traveller’s existence?
Hint: “Five threads on the loom, and only those where the old meeting happens can weave you in. Pick a strand at random—how likely is it that you don’t fade from the family portrait?” – Only numbers, no symbols.
